>> It doesn't seem sluggish to me at all (Luck?),
This was what was causing my sluggishness - A large amount of errors that started at exactly 3pm.
Browsing was excruitonatingly slow and pages would take a long time to load. It was extremely noticeable and like being on dial up, you couldn't not notice it. I had in excess of 20k Errored Seconds, so I am fully expecting the DLM to do what it does some point before tomorrow lunch time.
This originally started after an over-night outage where I had no sync for about 15mins. Prior to that the SNRm would practically be a nice straight line with a very occasional shift in SNRm of a fraction of 1dB.
Now it can spike anything between 3db. Its behaviour is very pulse like. I attach a graph below which whilst only showing small fluctuations in the downstream, you can see the pulse effect quite clearly on the upstream. Sometimes its way more jagged than this, but I chose this snapshot because it was during a period whilst the line was more stable but you can see how regular the oscillations are.
This isn't really what I'd class as typical REIN behaviour, there's no sharp drops at certain times. It's not SHINE, it could possibly be PEIN. I guess I need to go buy a radio. There's nothing that switched on here at 3pm. In fact the only thing that would have been on at that time would have been the PC. Neighbour is away a lot, all I know is that she only has adsl2 and couldnt get sync for several days. My own line was more stable during the period she didnt have sync but it could just be co-incidence that mine started acting up again after hers was fixed. Occasionally it will clear when I reboot, mostly it won't.
The thing is it seems stable now, but DLM will still kick in regardless, just like it did last time.
